crankshaft oil slinger
WO375877
Crankshaft oil slinger
For 134ci L-head and F-head engines
Oil slinger for the crankshaft of the 4-134 engine. This thin metal disc prevents excessive oil pressure on the front crankshaft seal by deflecting oil away from the timing chain. Essential component for reliable timing cover sealing.

Features
- Protects the front crankshaft seal against excessive oil pressure
- Prevents oil leaks at the timing cover
- Suitable for both chain and gear drive
- Fitted between crankshaft snout and pulley
- Replacement part for 4-134 engines
★ Quality component for the 134ci engine — both L-head 'Go Devil' and F-head 'Hurricane' versions.
Installation notes
The oil slinger is fitted onto the crankshaft snout, in front of the front seal. It sits clamped between the crankshaft shoulder and the pulley. Ensure the slinger lies flat and is not distorted — a bent slinger can contact bearings. Check crankshaft end play after fitting.
Compatibility
Fits all 4-134ci engines (L-head and F-head). Suitable for engines with chain drive (early MB/GPW/M201/early CJ-2A) and gear drive (late CJ-2A/CJ-3A/CJ-3B/M38). Used in combination with timing cover seal 931634.
Historical context
The oil slinger was standard fitment on all WWII and post-war 134ci engines. Without this slinger, the crankshaft seal would be overloaded by the high oil pressure from the timing chain lubrication and would leak.
